As shown in Figure 2, one implementation of this request provides a 200 method for processing a sensing service. The method can be implemented by a Sensing Control Function (SCF). The method includes the following steps. S202: The SCF receives a detection service request message sent by a first device. In this embodiment, the SCF can be configured to control a sensing device to obtain sensing measurement data, and based on the sensing measurement data reported by the sensing device, the SCF can further perform some data processing (e.g., data analysis) to obtain a sensing result.

Optionally, at this stage, the SCF receiving the detection service request message sent by the first device includes one of the following: (1) The SCF directly receives the detection service request message sent by the first device, where the first device includes an AF application function or a consumer terminal device. (2) The SCF receives, through a Network Exposure Function (NEF), the discovery service request message sent by the first device, where the first device includes an AF application function or a consumer terminal device. In this example, the consumer terminal device can send the discovery service request message to the AF, and the AF sends the discovery service request message to the SCF via the NEF; or, the consumer terminal device can send the discovery service request message to the AF, the AF sends the discovery service request message to an access and mobility management function via the NEF, and the access and mobility management function can send the discovery service request message to the SCF.

S502: The sensing terminal device obtains a URSP sent by a policy control function, where the URSP includes a corresponding data path selection policy according to which the sensing terminal device sends sensing measurement data to an SCF. S504: The detection device sends detection measurement data to the SCF according to the URSP. In this implementation, the detection terminal device receives the URSP from the policy control function, where the URSP includes the corresponding data path selection policy according to which the detection terminal device sends the detection measurement data to the SCF; and the detection device sends the detection measurement data to the SCF according to the URSP. In this implementation, in addition to providing a data communication transmission function, the wireless communication system can also provide a detection function, to help implement the fusion of wireless communication and radar detection, thereby greatly reducing hardware deployment costs.Optionally, in one embodiment, the URSP includes at least one of the following corresponding route selection description information: flow description information corresponding to the detection service, detection measurement data, time information, and position information. The route selection description information includes at least one of the following information: Data Network Name (DNN) selection information, segment selection information (e.g., Single Network Slice Selection Assistance Information, S-NSSAI), PDU session type selection information, access type selection information (e.g., a 3rd Generation Partnership Project, 3GPP access type, a non-3GPP access type), and the like. Optionally, in one embodiment, the method by which the discovery terminal device obtains the UE URSP path selection policy sent by the policy control function includes: The discovery terminal device obtains, via an access and mobility management function, the UE URSP path selection policy sent by the policy control function; or the discovery terminal device obtains, via the SCF, the URSP sent by the policy control function. Figure 6 is a schematic flowchart of the implementation of a method for processing a detection service according to a realization of this request. The method can be applied on one side of a policy control function. As shown in Figure 6, Method 600 includes the following steps. S602: The policy control function determines a URSP corresponding to a sensing terminal device, wherein the URSP includes a corresponding data path selection policy according to which the sensing terminal device sends sensing measurement data to an SCF. S604: The policy control function sends the URSP to the detection terminal device. In this implementation of the application, the policy control function determines the URSP corresponding to the detection terminal device. The URSP includes the corresponding data path selection policy according to which the detection terminal device sends the detection measurement data to the SCF. The policy control function then sends the URSP to the detection terminal device. In this implementation, in addition to providing a data communication transmission function, the wireless communication system can also provide a detection function, facilitating the fusion of wireless communication and radar detection, thereby significantly reducing hardware deployment costs. Optionally, in one embodiment, the URSP includes at least one of the following corresponding route selection description information: flow description information corresponding to the detection service, detection measurement data, time information, and position information. Optionally, in one embodiment, the method further includes: The policy control function receives a policy request message sent by an access and mobility management function or the SCF, where the policy request message is used to request the corresponding URSP from the discovery terminal device. Optionally, in one embodiment, the policy control function sending the URSP to the discovery terminal device includes: The policy control function sends the URSP to the discovery terminal device via the access and mobility management function; or the policy control function sends the URSP to the discovery terminal device via the SCF. To describe in detail the method for processing a detection service provided in the realizations of this request, descriptions are provided below with reference to two specific realizations. Implementation 1 An architecture to which this embodiment is applicable is shown in Figure 7. An independent sensing service function network element (e.g., an SCF) can be deployed in a network, and a point-to-point interface (e.g., an Nx interface) or a service-based interface is provided between the SCF and an AMF. The Nx interface or the service-based interface carries the transmission of control signaling related to the sensing task (e.g., sensing service control information) and / or sensing measurement data. It can be understood that the Nx interface may alternatively have another name. In this embodiment, a new protocol stack, specifically an NR detection protocol (NR detection protocol, NRSP), can be added between the SCF and a detection terminal device (UE) based on an existing protocol stack. The NR detection protocol can be understood as a protocol by which the SCF controls a detection device to perform the detection measurement configuration and report the detection measurement data, and the NR detection protocol may alternatively have another name. As shown in Figure 8, this implementation may include the following steps: Stage 0: Optionally, the consumer terminal device (consumer UE) exchanges detection task information with an AF at an application layer, where the detection task information may include an identifier (ID) of the consumer UE and description information of a detection service. The information describing the detection service includes at least one of the following: (1) Detection service type information, where type information is used to define a detection service type and can be defined according to a physical detection range and a real-time requirement. For example, Type I represents a wide detection range and a high real-time requirement (delay-critical LSS); Type II represents a wide detection range and a low real-time requirement (LSS); Type III represents a small detection range and a low real-time requirement (delay-critical SSS); and Type IV represents a small detection range and a low real-time requirement (SSS). (2) Information about a detection object, where the detection object includes, but is not limited to, at least one of: an article, a device, a person, an animal, a building, a car, an environment, air quality, humidity, temperature and a specific area (i.e., a particular area). (3) Detection quantity information of the detection object, where the detection quantity information includes, among others, at least one of: a position of the detection object, a distance of the detection object, a speed of movement of the detection object, images of the detection object, a movement trajectory of the detection object, texture analysis of the detection object, and material analysis of the detection object. (4) Information on the purpose or use of the detection service, corresponding respectively to the second and third columns of Table 1 below. Table 1 Purpose of use of the application of the detection service (5) Granularity information (by EU or by area) of the detection service, for example, indicating whether the detection service is for a single user or for a group of users, or indicating that the detection service is for a target area. (6) Runtime information of the detection service, where the runtime information of the detection service can be determined as absolute time information (e.g., from 13:00 to 19:00, Monday) or relative time information (e.g., within the next month). The runtime information may include a start time, an end time, the duration, or similar. (7) Related reporting information (reporting information) of detection measurement data, where reporting information is used to define a condition for reporting detection measurement data, a reporting time, a reporting format, a number of times to report, and the like. The reporting condition can be triggered by an event or triggered cyclically. In the former case, the reporting condition also includes information describing the event (for example, determining that a user has entered a driving state); in the latter case, the reporting condition also includes information about the reporting cycle (for example, every five minutes). The reporting time is used to indicate a time interval within which the detection measurement data must be reported, and the reporting time may or may not be consistent with the previous detection service time. Additionally, the notification format is used to specify how the detection measurement data will be reported, for example, indicating that the detection measurement data will be reported in binary / text format, or similar. The number of times to report indicates whether the report is generated once or multiple times, and a specific number of times to report if the report is generated multiple times. (8) Quality of Service (QoS) information of the detection service (or referred to as the detection indicator). The QoS of the detection service includes, but is not limited to, at least one of: detection accuracy, detection error, detection range, detection delay, detection probability, and false alarm probability, where detection accuracy includes: distance resolution, imaging resolution, motion speed resolution, or angular resolution; and detection error includes: distance error, imaging error, or motion speed error. Optionally, the consuming UE can also direct the detection service range information to the AF to indicate that the detection service is being performed for the detection service object within a specified range. The range can be a relative position range (e.g., within 20 meters) or an absolute position range (Tracking Area Identity, TAI, Cell ID, and Area Description information (e.g., Tiananmen Square, Beijing)). For example, when the detection service granularity is TAI(s), it indicates that the detection service is performed within a range specified by the TAI(s); or when the detection service granularity is an Area ID, it indicates that the detection service is performed within a range specified by the Area ID. When there are multiple pieces of information, the ranges indicated by these pieces of information can be either consistent or inconsistent.If the ranges indicated by the plurality of information fragments are inconsistent, it indicates that the detection service is performed within a union set range of the ranges indicated by the plurality of information fragments. At this stage, the AF can know that the consumer UE requests to run the detection service corresponding to the detection service description information. Step 1a: The AF service server sends a discovery service request message to the network (the AMF or SCF) through a NEF, where the discovery service request message can carry discovery service description information. The detection service description information in stage 1a may be the same as or different from that in stage 0. If the detection service description information in stage 1a is different from that in stage 0, the AF actually extracts or generates the corresponding detection service description information in stage 1a based on the detection service description information in stage 0. Optionally, the discovery service request message also includes service object identifier information for the discovery service, for example, the consumer's EU ID, to indicate a user device identifier that triggers the discovery service, or to indicate a user identifier corresponding to the discovery service's service object. Optionally, the detection service's target range information is used to indicate the execution of the detection service for the detection service object within the range. The range can be a relative position range (e.g., within 20 meters) or an absolute position range (e.g., Tiananmen Square, Beijing). Optionally, if the AF has determined which discovery device(s) (including a discovery terminal device or an access network device) is to be used for a particular service object (consumer UE) or a particular target range, the discovery service request message may also include discovery device identifier information (including discovery terminal device(s) ID(s) or access network device(s) ID(s)). In one implementation, the AF can send the discovery service request message to the AMF via the NEF, and then the AMF forwards the discovery service request message to the SCF. This implementation might occur, among other scenarios, where multiple SCFs are deployed on the network and the AMF needs to select a suitable SCF from among them based on information such as the location of the consuming UE and the type of discovery service. In another implementation, the AF can directly send the discovery service request message to the SCF via the NEF. This implementation can occur, among other scenarios, when one or a relatively small number of SCFs are deployed on the network. It should be noted that, if the AF is an AF that an operator relies on, step 1a can be performed without the NEF. Step 1b: Optionally, the consumer UE can alternatively send the detection service request message directly to the network (the AMF or the SCF). The content of the detection service request message is similar to that of step 1a. In one implementation, the consuming UE can send the discovery service request message to the AMF using a NAS message, and the AMF then forwards the discovery service request message to the SCF. This implementation might occur, among other scenarios, where multiple SCFs are deployed on the network and the AMF needs to select a suitable SCF from among them based on information such as the consuming UE's location and the type of discovery service. In another implementation, the consuming UE can directly send the discovery service request message to the SCF. This implementation can occur, among other scenarios, when one or a relatively small number of SCFs are deployed on the network. After receiving the message in stage 1a or 1b, the following two stages can also be included: The network (an executing body can be the AMF or the SCF) selects a corresponding detection device (including the detection terminal device / access network device) for the detection service of the target service object (the consumer UE). The network (an executing agency can be the AMF or the SCF) selects a corresponding detection device (including the detection terminal device / access network device) for the detection service within the target range (target AOI). In the two previous cases, if the AMF selects the corresponding detection devices, the AMF may also send identifiers or address information corresponding to the detection devices to the SCF before the following steps are performed. Step 2: The SCF sends detection service related information (corresponding to the detection service control information in the previous implementations) to the AMF, where the detection service related information may include a detection service correlation ID, a detection device identifier, the detection service description information (optional), and detection service configuration information. Specifically, the SCF may invoke a Namf_Communication_N1N2MessageTransfer message to send the detection service related information. The detection service correlation ID can be used to identify a detection service session. The detection device identifier is used to notify the AMF of a device participating in the detection signal measurement. The detection device may include the detection terminal device and / or the detection access network device. The detection device information is typically sent if the SCF selects the corresponding detection device. For descriptive information about the detection service, please refer to the descriptions above for more details. The detection service configuration information is policy and control information formulated by the SCF for the detection service description. For example, the detection service configuration information includes specifically used detection measurement data, a detection resource, a configured QoS profile for the detection service (a bandwidth setting, a priority setting, a precision setting, and so on), a configured activation condition for the detection service, reporting information, and so forth. The detection measurement data mentioned above includes: a first type of measurement data K11 and a second type of measurement data K12. Specifically, the first type of measurement data K11 includes at least one of the following: K111, an H-channel array; K112, a Received Signal Strength Indication (RSSI); K113, a Reference Signal Received Power (RSRP); K114, Channel State Information (CSI); K115, power of each path in a multipath channel; K116, delay of each path in the multipath channel; K117, angle information of each path in the multipath channel; K118, Doppler broadening; K119, Doppler frequency shift; K120, a phase difference between a detection signal received by a first antenna and a detection signal received by a second antenna; K121, a delay difference between the detection signal received by the first antenna and the detection signal received by the second antenna;and K122, a characteristic difference between an I-channel signal and a Q-channel signal; It should be noted that the characteristic difference may be a phase difference or some other difference between the I channel signal and the Q channel signal. It should be noted in this document that the channel I signal and the channel Q signal are respectively an in-phase signal and a quadrature signal, where I is in-phase, Q is quadrature, and the phase difference between the channel I signal and the channel Q signal is 90 degrees. Specifically, the second type of measurement data K12 includes at least one of the following: K121, characteristic information of a target article, where it should be noted that characteristic information of the target article is information that may reflect an attribute or a state of the target article, and may be at least one of the following: presence of the target article, a distance from the target article, a position of the target article, a speed of the target article, an acceleration of the target article, a material of the target article, a shape of the target article, a category of the target article, a Radar Cross Section (RCS) of the target article, a polarization scattering characteristic, and the like;K122, related information of a target event, where it should be noted that related information of the target event is information related to the target event, i.e., information that can be detected / perceived when the target event occurs, and may be at least one of the following: fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip language recognition, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, and the like;and K123, related information of a target environment, where it should be noted that the related information of the target environment may be at least one of the following: humidity, brightness, temperature and humidity, atmospheric pressure, air quality, weather conditions, topography, distribution of buildings / vegetation, people count, crowd density, vehicle density and the like.; Optionally, the measurement data may also include at least one of the following: k21, a position, a material, a shape and / or a category of a reflection point; and k22, radar spectrum information. Optionally, the measurement data are measurement data for each antenna or measurement data for each detection resource (a time domain or a frequency domain, where the frequency domain includes one or more subcarriers, a Radio Bearer (RB), a Bandwidth Part (BWP), a carrier and the like). Step 3: The AMF sends the related detection service information (corresponding to the detection service control information in previous realizations) to the detection device. Step 3a: If the discovery device includes the discovery terminal device, the AMF sends the discovery service-related information to the discovery terminal device via a downlink NAS message. This discovery service-related information includes the discovery service correlation ID, the discovery device identifier, the discovery service description (optional), and the discovery service configuration information. Specifically, the discovery service-related information is encapsulated within the NAS message and transmitted transparently to the UE, making it potentially impossible for the AMF to parse. This method has two possible implementations. In one implementation, the detection terminal device, acting as the measurement executor for the detection service, performs a detection measurement on a detection signal received by the detection terminal device, based on the related detection service information sent by the AMF, to obtain the detection measurement data. In the other implementation, the detection terminal device configures a corresponding detection resource (e.g., a detection signal) based on the related detection service information sent by the AMF, and sends the detection signal to a network element used for detection measurement (including the UE itself, another detection terminal device, or the detection access network device), so that the other network element can obtain the detection measurement data. Step 3b: If the sensing device includes the sensing access network device, the AMF can further send sensing service related information to the sensing access network device by means of an N2 interface message, where the sensing service related information includes the sensing service correlation ID, the sensing device identifier, the sensing service description information (optional), and the sensing service configuration information. In one implementation, the discovery access network device sends a downlink discovery signal to the discovery terminal device based on information received from the discovery service. This allows the discovery terminal device to perform the corresponding measurement on the downlink discovery signal to obtain the relevant discovery measurement data. This implementation is generally applicable to a scenario where the discovery access network device uses existing Radio Resource Management (RRM) configuration information to control the discovery terminal device in order to measure certain existing measurement data (e.g., CSI, a Synchronization Signal and PBCH block, SSB, etc.).If the UE detects the downlink detection signal, the detection access network device can further notify the UE of the downlink detection signal configuration information, helping the UE to receive the downlink detection signal according to the configuration information. In another implementation, the detection access network device, acting as the detection service measurement executor, performs a detection measurement on a detection signal received by the detection access network device, based on the related detection service information sent by the AMF, to obtain the detection measurement data.The detection signal received by the detection access network device includes: a detection signal sent and received by the detection access network device itself, an uplink detection signal sent by the UE, or a detection signal sent by another access network device. If the detection access network device receives an uplink detection signal sent by the UE, it can notify the UE of the uplink detection signal configuration information in advance, helping the UE to send the uplink detection signal according to that configuration. The above configuration information for the detection signal may specifically include at least one of the following: (1) a waveform, for example, orthogonal frequency division multiplex (OFDM), single-carrier frequency division multiple access (SC-FDMA), orthogonal time frequency space (OTFS), a frequency modulated continuous wave (FMCW), a pulse signal, or the like; (2) a spacing between subcarriers: for example, a spacing between subcarriers of 30 KHz of an OFDM system; (3) A guard interval: a time interval between the moment when the transmission of a signal ends and the moment when a final echo signal of the signal is received; this parameter is proportional to a maximum detection distance; for example, the guard interval can be calculated by 2dmax / c, where " / " in this document represents a division operation, and dmax represents the maximum detection distance (which belongs to the detection requirements); for example, for a detection signal sent and received by the detection device itself, dmax represents a maximum distance between a point of reception of the detection signal and a point of transmission of the signal; and, in some cases, a cyclic prefix CP of an OFDM signal can serve as a minimum guard interval; (4) a bandwidth: this parameter is inversely proportional to a distance resolution, and can be obtained via c / (2*delta_d) , where " / " here represents a division operation, "*" represents a multiplication operation, delta_d represents the distance resolution (which belongs to the detection requirements) and c represents the speed of light; (5) Burst duration: This parameter is inversely proportional to a rate resolution (which belongs to the detection requirements), and this parameter is a time interval of the detection signal, mainly for the purpose of calculating a Doppler shift; this parameter can be obtained by dividing c by a first parameter value, which is a product of 2delta_v and fc, where delta_v represents the rate resolution; and fc represents a carrier frequency of the detection signal; (6) a time domain interval: this parameter can be obtained by dividing c by a second parameter value, which is a product of 2fc and v_range, where v_range is a maximum speed minus a minimum speed (which belongs to the detection requirements); and this parameter is a time interval between two adjacent detection signals; (7) transmission signal power, for example, a value taken every 2 dBm from -20 dBm to 23 dBm; (8) a signal format, for example a probe reference signal (SRS), a demodulation reference signal (DMRS), a positioning reference signal (PRS) or similar, or other predefined signal, a related sequence format and other information; (9) a signal direction, for example, direction or beam information of the detection signal; (10) a time resource, for example, an index of a slot in which the detection signal is located or a symbol index of the slot, wherein the time resource is divided into two types, one being a unique time resource, for example, a symbol sends a first omnidirectional signal, and the other being non-unique time resources, for example, a plurality of periodic time resource groups or discontinuous time resources (which may include a start time and an end time), each periodic time resource group sending detection signals in the same direction, and the beam directions in different periodic time resource groups are different; (11) a frequency resource, including a center frequency, bandwidth, RB or subcarrier, Point A, start bandwidth position or the like of the detection signal; and (12) a quasi co-location (QCL) relation, e.g. the detection signal includes a plurality of resources, each resource corresponds to an SSB QCL, and the QCL includes Type A, B, C or D. Similarly, in a case where the discovery access network device sends and receives the discovery signal itself, it can also configure the discovery signal beforehand, so that it sends the discovery signal according to the configuration information. For configuration information for the discovery signal sent and received by the discovery access network device itself, refer to the UE uplink discovery signal configuration information in the preceding text. Similarly, if the detection access network device receives a detection signal from another access network device, the detection access network device can also configure the detection signal for the other access network device in advance (or the SCF sends the detection service control information to the other access network device via the AMF to configure the detection signal), so that the other access network device sends the detection signal according to the configuration information. For the detection signal configuration information, refer to the UE uplink detection signal configuration information in the preceding text. Step 4a: The detection terminal device performs the detection measurement according to the related detection service information to obtain the detection measurement data. Step 4b: The detection access network device performs detection measurement according to the related information from the detection service, to obtain the detection measurement data. In another example, step 4b can be modified as: The access network device instructs the detection terminal device to perform the detection measurement. Specifically, the detection terminal device either sends and receives the detection signal itself or receives a downlink detection signal sent by a Radio Access Network (RAN), and performs the detection signal measurement to obtain the corresponding detection measurement data. Step 5: The detection device sends the detection measurement data to the AMF. When the detection device is the detection terminal device, this stage has two possible implementations: Step 5a: The detection terminal device sends the obtained detection measurement data to the AMF via an uplink NAS message. Steps 5b and 5c: The detection terminal device sends the obtained detection measurement data to the access network device via a Radio Resource Control (RRC) message, and the access network device sends the detection measurement data to the AMF. When the detection device is the discovery access network device, this step has one possible implementation: Step 5d: The detection access network device sends the detection measurement data obtained by the detection access network device to the AMF using the N2 interface message. Step 6: The AMF forwards the detection measurement data reported by the detection device to the SCF. Specifically, the AMF can forward the detection measurement data to the SCF using a Namf_Communication_N1InforNotify message. Step 7: Optionally, the SCF obtains an analysis result from the detection service in accordance with the detection measurement data. Specifically, the SCF can perform the corresponding computational analysis based on an internally configured algorithm specific to the type of detection service, to obtain the result of the detection service analysis. For example, the detection service result could be information about the user's respiratory health status (whether breathing is abnormal, the degree of abnormality, or similar), or information about traffic hazards in the neighborhood (whether there is a sudden appearance of a pedestrian, the probability of appearance, and the time), or similar information. Certainly, the algorithm can be an intelligent algorithm based on artificial intelligence (AI), and the algorithm can come from an external intelligent entity or from its own AI model training. Step 8: The SCF sends the detection measurement data and / or the result of the detection service analysis to the AF. Subsequently, the AF may also send the detection measurement data and / or the detection service analysis result to a consumer terminal device. Alternatively, step 8 may be replaced by the following: The SCF sends the detection measurement data and / or the detection service analysis result to a consumer terminal device. Implementation 2 Figure 9 shows an architecture to which this embodiment is applicable. An independent sensing service function network element (e.g., an SCF) is deployed in a network. A point-to-point interface (e.g., an Nx interface) or a service-based interface is provided between the SCF and an AMF, and a point-to-point interface (e.g., a Ny interface) or a service-based interface is provided between the SCF and a User Plane Function (UPF). The Nx interface or the corresponding service-based interface carries the transmission of control signaling related to the sensing task. The Nx interface or the corresponding service-based interface carries the transmission of sensing measurement data. It can be understood that the Nx or Ny interface may each have a different name. In addition, the AMF interacts with the UPF via a Session Management Function (SMF). In this embodiment, a new control plane protocol stack can be added between the SCF and a sensing terminal device (SU) based on an existing protocol stack, to control the transmission of control signaling related to the sensing task; and a new user plane protocol stack can be added between the SCF and the sensing terminal device (SU), to control the transmission of sensing measurement data. Steps 1 to 4 in this embodiment are similar to steps 1 to 4 in Embodiment 1. As shown in Figure 10, the difference lies in the following points. Optionally, at any time prior to step 4, a network Policy Control Function (PCF) can send one or more new UE Route Selection Policies (URSPs) to the UE via the AMF, where the URSP is used to instruct the UE to transmit network-related sensing service measurement data via a particular PDU session or to instruct the UE to offload measurement data to a non-3gpp tunnel for transmission to the network. In one example, in step 3a, the related information from the detection service carries the URSP. Alternatively, in steps 3b and 3c, the related information from the detection service carries the URSP. This step can take place in a procedure where the detection terminal device is registered on the network, or at another time when the URSP corresponding to the detection service must be delivered after registration is complete. In one example, in step 1a or 1b, when the detection service is activated, the AMF or SCF can request, from the PCF, the URSP corresponding to the detection terminal device, and the AMF / SCF sends the obtained URSP to the detection terminal device through step 2 or 3a. If a discovery service has multiple URSPs, these URSPs can be prioritized. Furthermore, the URSPs can correspond to different measurement data within the discovery service. Specifically, the URSP instructs the UE to route different measurement data within the same discovery service to different PDU sessions or to offload different measurement data within the same discovery service to a non-3GPP tunnel. Optionally, the URSP includes at least one of the following corresponding route selection description information: flow description information corresponding to the detection service, detection measurement data, time information, and position information. The flow description information for the discovery service includes at least one of the following: discovery service type information, discovery service identifier information (for example, a discovery service application ID); an Internet Protocol (IP) / non-IP address corresponding to a discovery service server; and port number information corresponding to the discovery service. Step 5: Optionally, if the detection terminal device determines that there is no PDU session that can be used to transmit the measurement data corresponding to the detection service, the detection terminal device initiates a PDU session creation / modification procedure. If the sensing terminal device determines that an existing PDU session can be used to transmit the corresponding measurement data to the sensing service, it is not necessary to initiate this step. Step 6: The detection terminal device sends the detection measurement data to the UPF using a PDU session user plane tunnel. The UPF forwards the detection measurement data to the SCF using the Ny interface between the UPF and the SCF. Stages 7 and 8 are the same as those in Implementation 1. Subsequently, the AF may also send the detection measurement data and / or the detection service analysis result to a consumer terminal device. Alternatively, step 8 may be replaced by the following: The SCF sends the detection measurement data and / or the detection service analysis result to a consumer terminal device. It should be noted that the method for processing a detection service provided in the embodiments of this request may be performed by a detection service processing device, or by a control module located in the detection service processing device and configured to perform the detection service processing method. In the embodiments of this request, an example is used in which the detection service processing device performs the detection service processing method to describe the detection service processing device provided in the embodiments of this request. Figure 11 is a schematic structural diagram of an apparatus for processing a detection service according to one embodiment of this application. The apparatus may correspond to an SCF in another embodiment. As shown in Figure 11, an 1100 apparatus includes the following modules: a 1102 receiving module, configured to receive a detection service request message sent by a first device; a sending module 1104, configured to: send detection service control information to a detection device, wherein the detection service control information is generated by the apparatus in accordance with the detection service request message, and the detection service control information is used to instruct the detection device to obtain detection measurement data; and The 1102 receiving module is also configured to receive detection measurement data sent by the detection device. In this execution of this request, the receiving module receives the detection service request message sent by the first device. The sending module sends the detection service control information to the detection device. The detection service control information is generated by the device according to the detection service request message and is used to instruct the detection device to obtain the detection measurement data. After the detection device performs the detection measurement to generate the detection measurement data, the receiving module can also receive the detection measurement data sent by the detection device.In fulfilling this application, in addition to providing a data communication transmission function, a wireless communication system can also provide a detection function, to help implement the fusion of wireless communication and radar detection, thereby greatly reducing hardware deployment costs. Optionally, in one embodiment, the detection service control information is further used to indicate at least one of the following: the detection device configures a detection measurement resource; and the detection device performs the detection measurement.
